Definitions

  • the concentration of acetic acid and citric acid with surfactant blend is such that the composition does not exhibit herbicidal properties on cucumbers or tomatoes.
  • a preferred method of the present invention for the treatment of a fungus on a vegetable, flowering plant or tree comprising the steps of preparing an aqueous fungicide composition described herein and applying an effective amount of said aqueous composition to said fungus.
  • One aspect of the present invention relates to methods for the treatment of a fungus and use of aqueous fungicidal compositions of acetic and citric acid in combination with an anionic/non-ionic surfactant blend.
  • the combination of acetic and citric acids with an anionic/non-ionic surfactant blend exhibits synergistic effects as a fungicide, with the resulting composition being more effective as a fungicide than a corresponding composition of acetic acid, citric acid or surfactant alone at the same concentration or a combination of only two of acetic acid, citric acid and surfactant.
  • the fungicidal composition may be formulated so as to be effective on one or more of a variety of fungus.
  • the composition may be used in the treatment of powdery mildew.
  • the composition may be used on a variety of plants, including vegetables and flowering plants, as well as on trees.
  • Leaf damage of 10% or lower is preferred. This usually occurs as leaf curling or leaf tip burn on older leaves but not on new ones.

Abstract

L'invention concerne une composition aqueuse d'acide acétique et d'acide citrique combinés à un tensioactif destinée à être utilisée comme fongicide. Cette composition peut être utilisée pour traiter des champignons affectant des légumes, des plantes à fruit ou des arbres.
